The measure of angle C is 130°
Here’s a little trick:
The names of both figures maps to the corresponding letter. So, in MRDLP, P maps to C in HJOBC. This is because both P and C are the last letters of the figure. The same is true of any other letter, such as M. Angle M maps to angle H. This trick works most of the time because corresponding points of Congruent figures must be named in corresponding order.
